3. Sera placed 200 g of dry ice in a bucket and left it near the window. She returned after 5 days to find nothing was left in the bucket. Assuming that all ice had melted and evaporated over the 5 days, determine how much energy was used by the ice to completely evaporate. Specific heat of water = 4200 Jkgloc-1 Latent heat of vaporisation of water = 2.3 × 10 Jkg Latent heat of fusion of ice = 340 000 Jkg -1 -1

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

where’s the list ? the question is incomplete
